IMPROVED COMPOUND OR YROUG-H STUFF TO BE APPLIED TO CARRIAGE-BODIES, 8m.

The Schedule referreddoiu these Letters Patent and making pa t Of t e s me To all whom it may concern:

Be it known that I, EDWARD SCIIARNIKOW, of Margarettville, in the county of Delaware and State of New York, have invented a new and improved Compound for Rough Stuff ;-and I-do hereby declare the following to be a full, clear, andv exact description thereof, which will enable those skilled in the art to make and use the same.

This invention relates to a compound which is technically known as tough stuff, and which is applied to carriages, car-bodies, and other-articles to be varnished, previous to theapplication of the coat ofvarnish, for the purpose of producing a smooth'snrface for the reception of the varnish.

My compound is made-of brown clay, prepared linseed-oil, varnish, and japan, which ingredients are 'mixed together in about the following proportion:

Brown clay, five parts; prepared linseed-oil,- one part; varnish, one part; japan, three parts. The clay is cleaned from all impurities by washing,

and the linseed-oil is prepared with litharge,'au1ber,

red lead, and sugar of lead, in the following manner: Totive gallons of linseed-oil I add half a poundof lead, and a quarter pound sugar of lead, and boil the mixture twice, so as to produce a homogeneous mass.

After having prepared the clayandthe linseed-oil, I Inixahem together with hard-drying varnish and japan, in about-the proportion above stated, and I obtain a rough stuff which, when applied to the article to be varnished, produces a perfectly smooth and level surface, and which is elastic and very durable, so that itis not liable to crack or flake oil. It does not absorb the varnish, and produces a brilliant finish, and it saves time, labor, and expense. 4 What I claim as new, and desire to secure by Letters Patent, is A compound for rough stuff, made of the ingredients herein set forth, and mixed together about in the proportion and in the manner above described.

This specification signed by methis 22d day of v January, 1870.
